Patent DE-2712485-A1 (DE)
Title: Paper web connection and tooling unit - uses rotary cutter blades working in thermoplastics thread guide slots to hook thread through web slits
Inventor: DOSTER KARL DIPL ING
IPC: B31F5/00
Filed: 1977-03-22
Abstract: Releasable connection for two paper webs consists of a thermoplastic thread which is passed through two parallel slits in the web movement direction and joined to the bottom web so that fused on thread ends point backwards relative the direction of movement and the releasably joined webs can adjust slightly relative to one another along the length of the slit. The connection is produced by a rotary cutter (1) parallel and synchronised with the web movement below the bottom web (2) and fitted with three parallel blades (3, 8, 12). Blades (8) should cut in the upwards direction but form hooks below. Above the web the cutter has a thread guide (3) whose through bore (4) is interrupted by the slits (5, 6, 7), the guide being recessed to the centre of the bore to take the radius of the hold-down roller (13). Thus the blades should cut into the slits, blade (12) working first so as to cut the thread (16) for hooking up by the blades (8) and led thus through the slit web.

Title: Barium titanate ceramic tubes metallisation - by dipping into silver suspension ultrasonically vibrating and extracting from suspension at specified rates
Inventor: WILDONER PETER
IPC: C23C24/00
Filed: 1977-04-27
Abstract: Rectangular or flat tubes, made of ceramic materials, e.g. barium titanate ceramics, are metallised by dipping into a suspension of silver particles, adhesive oxides and suspension agents, followed by drying and firing. The dipping operation proceeds at a speed of 6-10 cm/s and is followed by 15 seconds of ultrasonic vibrations. The tubes are withdrawn at a speed of 1-2 cm/s. This speeds up the whole operational cycle. The tubes are metallised uniformly with a continguous and well adherent coating and with a min. consumption of silver. The whole cycle can be readily automated. Used in prodn. of barium titanate ceramic tubes with faultless silver coating for capacitor dielectric media.

Title: Dry cleaning system with solvent gases - has controlled drying temp. automatically set by using heat from gases in heat exchanger
Inventor: SIEBER JOHANNES HELMUT
IPC: F26B23/00
Filed: 1977-05-28
Abstract: Articles such as textiles which have been treated with volatile organic solvents are dried in a closed vacuum chamber or drum (1). The solvent gas enclosing the articles passes in a circuit from the goods over a heat exchange element (5) and back to the goods. The same solvent gas removed from the circuit is compressed outside the chamber in a condenser (8) and heated then fed as the heating medium through the inside of the heat exchanger element (5). The solvent gases which circulate through the machine where they are used for drying are thus heated by the heat content of the gases drawn off from the processing chamber and gas circuit, this heat content being increased by the compression warmth.

Title: Responder system for relatively movable radio stations - has waveguide section for each responder to which exchangeable resonators may be connected
Inventor: GARBRECHT KURT DR
IPC: G01S13/75
Filed: 1977-05-31
Abstract: The responders can automatically transmit multiple digit radio signals, esp. numbers of railway coaches, between movable w.r.t. ea each other interrogation station and responder. Each interrogation station transmits in a certain microwave frequency band an interrogation signal whose frequency varies periodically. The response signal selects by a filter consisting of h.f. line resonators, frequencies allocated to the information, and sends back to the interrogation station a specified number of reply frequencies for each digit. Each responder has a waveguide section, to which the filters for the frequencies to be selected are coupled, and resonators for all frequencies provided. The resonators (7) are permanently tuned and can be removed from the waveguide (6) which has recesses (9) for each resonator. Locking devices are provided for secure holding and contacting the resonators (7).

Patent DE-2749230-A1 (DE)
Inventor: DOERING ERICH
IPC: E04F13/08

Abstract: In order to fasten dimensionally stable insulating panels (10) on the inner side of hall walls comprising profiled sheet-metal panels (11), engaging one in the other at the edges or butt joints by means of rabbets or a bent-over portion, use is made of a profiled-sheet-metal securing means (1) which can be fastened on the inner side of the sheet-metal panels (11) and, in each case together with a neighbouring profiled-sheet-metal securing means (1), receives the insulating panels (10). The profiled-sheet-metal securing means (1) is designed as an angle rail having a length virtually corresponding to the width of the profiled-sheet-metal panels, having a back-type leg (2) parallel to the hall wall and having a load-bearing leg (3) which projects at right angles from said back-type leg (2) and has supporting tabs (4) bent-off at right angles. At the two ends of the back-type leg (2), said securing means has retaining tabs (6, 7) which are angled off or can be angled off and have, at the edge, in each case a bent-over a portion (8, 9), each of which runs in the same direction as the other. These bent-over portions (8, 9) permit the retaining tabs (6, 7), for the purpose of fastening the profiled-sheet-metal securing means (1), to engage around the free edge (13) of the profiled-sheet-metal panels (11). <IMAGE>

Title: Recording hologram on photothermoplastic material - using polymer e.g. polystyrene, with definite mol. wt. distribution, for easy control of frost
Inventor: REICH SHYMON
IPC: G03G16/00
Filed: 1977-11-21
Abstract: Recording holograms in a photothermoplastic material involves giving the recording material a pattern is produced on the photoconductor, recharging the exposed areas and developing by heating near the temp. at which the medium reaches its plasticity point and cooling rapidly below this point, so that surface deformation occurs, proportional to the light intensity. The novelty is that the frost phenomenon is controlled by the use of a polymer with a definite mol. wt. distribution Mw/Mn, where Mn is the no. average mol. wt. and Mw and wt. average mol. wt. The system is suitable for real-time in-situ and image formation purposes and the frost phenomenon can be controlled easily and eliminated if necessary. Specifically, a 0.25-10 mu m thick monocomponent polymer is used, with Mw/Mn 1.2 for frost redn. Mw/Mn 1.08 for frost elimination. For thermoplastic xerographic holography using the frost phenomenon, a mixt. of polystyrenes, pref. of mol. wt. 900-40,000 is used.
Patent DE-2752922-A1 (DE)
Title: Film-type resistor with laser-cut helical gap in resistance film - is constructed using ceramic cylinder with pitch of film helix smaller at centre
Inventor: HORSTMANN HANS-WOLFRAM
IPC: H01C17/24
Filed: 1977-11-26
Abstract: The film-type resistor (1) consists of an insulating cylinder with a resistance film forming a helix along it and connected at the ends to contact caps. The helix is formed by cutting a helical gap with a laser beam into the film covering the entire cylinder. The pitch of the helix increases as one end in approached -- or as both ends are approached. The advantage of having a smaller pitch at the centre (or at one end) lies in increasing lifetime and permitting smaller tolerances for the resistance.

IPC: H04M7/14
Filed: 1979-03-30
Abstract: A telephone system has central and decentralised contol appts. and a traffic link between identical and different installations, one such installation being associated with a coupling network which provides links between decentralised control apparatus, and a central control with information transmission line network and a central audible signal receiver for evaluation of audible signs appearing by way of a call-office. After occupation of a set of link lines and selection of an indicator or separation prefix evaluated by a central control and received by way of a selection set, the connection of a central audible sign receiver at the call line link is initiated as is the prevention of retransmission of the call selection subsequently selected and appearing by way of the link line set, and their intermediate storage in a particular memory. After reception of an audible sign appearing by way of the occupied link line set ad evaluated by the audible signal receiver, the retransmission of the stored call selection is controlled from the central control.
